now, if I need to avoid certain versions of those tools, that's when a frozen 'do not update' VM would make sense. I'd fetch the magic versions, do the install and consider that a dedicated build system that never gets updates unless there's a reason for it.

but if I can always use 'current' for those tools, that means I can use my everyday workstation (3.19 kernel, some version of MINT that is recent enough) and just layer what I need on that, directly.

sounds like the ARM tools should be installed and then locked down, since those are the critical ones.

when I get my 2nd 7e, I'll be brave enough to do a local build and local flash. not on my daily driver until I have been thru this a few times

edit: only thing my main linux box didn't have, from that list, was mercurial. and I don't have ARM installed, yet, either.]]>TutorialsThu, 17 Mar 2016 19:40:47 +0000How to set up FBL helis on Custom Firmware - by: Tom Zhttps://www.deviationtx.com/forum/how-to/1226-how-to-set-up-fbl-helis-on-custom-firmware?start=20#20345

I thinks that : The 3 mode of 1st can using mix complete with Complete Mix.
And 3 mode after can using curvetype=add, This case, using add DR1 with one of value to Fmod.
I using Mix by case for 4 channel is correct, so with 5 and 6 are wrong way, because it make some channel before is fail.
If we can using this mix Case, we just using 2 switchs.

I bought a devo F12E with the Walkera Scout x4 last year and wish to bind my other FPV quadcopter with DSM2 receiver.
I tried to upgrade the deviation firmware using the following guideline.

Now, I have questions regarding the entire firmware upgrade procedure.
Is the upgrade requires two steps?
1) using the steps mentioned above by tools lile (DFU USBDrv Installer-1.1.zip and DeviationUpload-0.8.0.jar etc.);
2) use this link
www.deviationtx.com/wiki/installing_on_f_series
to complete the second step.

OR I totally wrong about that!!!

https://www.deviationtx.com/forum/how-to/1436-add-two-switches-to-the-devo-7e?start=200#62752

The long handle toggle switch on the right (SwB) is a 3 position switch.

The long handle toggle switch on the left (SwA) is a 2 position switch.

Plus I have added a momentary button switch on the upper left of the back shell.

This exact configuration isn't quite supported by the current firmware, But enabling it using extra-switches=3x2 in the hardware.ini file is very very close.

This works fine as long I remember to reference only A0 or !A0 in my models.ini files for the 2-pos toggle, and A2 or !A2 for the momentary button. I need to avoid referencing A1 or !A1 because both the 2-pos toggle, and the button alter these values. That would lead to unexpected behavior, if I think of the button and the switch as independent controls.

Switch B behaves exactly as intended.

Let me know if part numbers, schematic, or picture of the wiring would be helpful to someone wanting to do a similar configuration.]]>TutorialsFri, 02 Jun 2017 02:17:14 +0000Devo7e - 4in1 - S-FHSS - Frequency Issue - by: mwmhttps://www.deviationtx.com/forum/how-to/6962-devo7e-4in1-s-fhss-frequency-issue#60970

https://www.deviationtx.com/forum/how-to/6946-elevator-stick-as-a-flip-flop-switch-for-dlg#60116
I like to switch the flight mode during DLG start by moving the elevator stick over a defined position. At the highest point I want to switch from START to NORMAL without touching an extra knob.

I found a way to do this, the switch acts like a flip; reset (flop) is done by the unused trim-knob.

How it works:

on the mixer:
select an unused virtual channel, rename it for better understanding (e.g.: TRM-SW)
set the type to 'complex'
set the source to 'TRM-SW'
set the Curve to '1to1'
set the scale to '0'
set the trim button to 'Trim'
SAVE

Next:
on the trim page:
select the unused TRIM (THR)
set the INPUT to an unused virtual channel (TRM-SW)
set the step to 'Momentary'
set the Trim+ to the trim in question
set the Trim- to None
SAVE

Now the Flip-switch:
on the mixer:
select an unused virtual channel, rename it for better understanding (e.g.: FH1, flip helper 1)
set the type to 'complex'
set the Source to 'elevator'
set the Curve to 'MIN/MAX'
Enter 'MIN/MAX'
set the switch value to desired (e.g. '50'), SAVE ; here you define the switch point
set the scale to '100'
set the trim button to 'NO Trim'
SAVE

now do the same same with a second virtual channel:
select an unused virtual channel, rename it for better understanding (e.g.: FH2, flip helper 2)
set the type to 'complex'
set the Source to 'elevator'
set the Curve to 'MIN/MAX'
Enter 'MIN/MAX'
set the switch value to desired (e.g. '50'), SAVE ; here you define the switch point
set the scale to '100'
set the trim button to 'NO Trim'
SAVE

now the FLIP:
select an unused virtual channel, rename it for better understanding (e.g.: FLIP)
set the type to 'complex'
set Mixers to '2'
goto page 1
set the Switch 'FH1'
set MUX to 'replace'
set the Source to 'FH2'
set the Curve to '1to1'
set the scale to '100'
set the trim button to 'NO Trim'
SAVE
goto page 2
set the Switch 'TRM-SW'
set MUX to 'replace'
set the Source to 'FH1'
set the Curve to '1to1'
set the scale to '100'
set the trim button to 'NO Trim'
SAVE

That's it. Now you can use the FLIP channel as a switch for whatever, reset by unused trim knob.

That should solve the Missing Modules error. If not, then we need to see your Hardware.ini file settings and we need to know the pads where you wired the 4-in-1 into the radio.

I'm going to open up my Devo and review my connections and .ini based on this thread.

I appreciate the pointers, gdenton and arnold!

EDIT
My connections match up with ones shown in the thread.
I changed my hardware.ini file to match the one shown in the thread.
Now restarting normally.

I really appreciate the help. thank you so much!

The only way I can test the functionality of the other modules is to find or create the model files for the other flyers I have.
DSMX works.
V2X2 protocol is first on the list of others with Hubsan and Bayang Toys being next.

EDIT #2

I set up some quickie model files for each of the protocols I listed and I have been able to fly each accordingly!

So far I would say that the multimodule is being seen and is operating.
I haven't done any range tests with it yet but that's next.

Which Devo system are you using; B&W button nav or colour touch nav? (10/7E vs 6/8/12)? Which release?
Which template exactly are you using?

I'm not sure if it's a software issue or perhaps your methodology, as so ar I haven't been able to emulate what you've described. But it could be a case of being too familiar with the interface and being blinded to how someone who's unfamiliar would navigate. Do you add a second mixer, navigate to page 2, then add the source? Even if you didn't do this and replaced the source on channel one, I'm not seeing any way that can affect channel 2, so I'm a bit stumped. I don't suppose you could chuck up a quick video?

I do fly planes, but I'm not familiar with a setup that has "ailerons linked physically to the elevator"; seems you aren't just talking about elevons, with a software mix, but something that's doing physical mixing as well? I'm probably searching for the wrong terms but I couldn't find an example of such a setup.
If it is just elevons, eg. for an F15 (aka. "tailerons"), then there's a few examples around her, otherwise I can give some pointers and/or share some of my inis.]]>TutorialsSun, 30 Oct 2016 23:34:00 +0000Need help to setup switch on devo 7e - by: Alexandrohttps://www.deviationtx.com/forum/how-to/6520-need-help-to-setup-switch-on-devo-7e#55518

I tried this and some variations of what I thought would work and it does almost do what I want. With this config and anything else I have tried I can get the sticky throttle to disengage at 35% OR LOWER, problem is I can't figure how to make it so it only works at 35%.

Thanks for the info, i just installed it as normal as a seperate module.

On a side note, it seems that if you accidentally connect one of the aux knobs chasis to the nrf24l01 arial ground, the devo 10 shuts of when you turn the knob up full.

now when you go in, you will have 3 rates and expo you can set , note that only 2 of the rates have an option to assign to a swtich, so the one with no switch (high rate) will be active when niether of thos switches is on. on a devo 10 i have mix 1 on mid rate, and mix 0 on low, so when i switch to mid 2 it gets high rate.

not sure how it works on the 7e, mabe ignore the high rate and just use mid and low, and asign to a 2 position switch.

Thanks for the answer(s) and @slipstream,: I totally understand the perils of writing a tutorial thread(s). Perspective gets you every time sooner or later.

One note, the toggle3.bmp file is used to provide additional user-created icons on the screen; by convention users can modify or replace this file as they wish (it lives in the media folder). The one he is using is for a color Devo 8 or 6, so it won't work with your Devo 10, and the selections are already in this ini file. You may see blanks or question marks instead of icons. You can fix them by choosing different icons (model menu, main page config, arrow down to the "Toggle1", or other toggle button and hit enter). You can also search this forum for additional toggle3.bmp alternatives for the Devo 10.

Good luck and let us know how it goes, ask questions, whatever. If you make changes, please post your new config to the Model Configs topic area!

The concept is that you devide 150 / 2 and use 75% of travel (like DX8 airware does it) for AIL + 75% of travel on ELEV.

I just used the elevon tutorial having REPLACE + ADD MUX mixers (4 in total).

This kind of tutorial makes the platform accessible to all. So much so that that the Deviation software should include ready-to-use example ini files for different types of aircraft (eg 4 ch, 6 ch, 3 axis, 6 axis, fp, cp, etc); anything which has been tested and found working should be included, along with a short description of the functional characteristics implemented.

These are called "templates" and they are already in the distribution. It includes 4 and 6 channel models as well as a dual rates tem!plate and a generic helicopter. If you want to add more, please create a pull request for them.

The library is also a great idea, and had been discussed before. But somebody needs to do it. I could, but I'd rather work on things like the extra switches and vice alerts code, and suspect many users would would prefer I work on those as well. So someone else needs to step up and do it.

One with the released version 4.0.1 (
www.deviationtx.com/downloads-new/category/12-deviation-4-0-1
)

It would be really nice if when in Loiter mode i could flick a switch and then my right stick (Roll/Pitch) became Pan/Tilt on the camera gimbal

This is possible, assuming that there are four channels involved: the two standard elevator and aileron channels, and two more for gimbal roll & pitch control.

First step is to get the switch working. What we want is a switch that is "on" if some control is on when in loiter mode, and off if that other control is off and you aren't in loiter mode. So two more assumptions: flight mode is controlled by the FMODE switch with loiter mode being FMODE2, and we're going to enable gimbal control with the GEAR1 switch.

To "and" two controls this way, we need a virtual channel that goes on when they are both on, and is off otherwise. So set a virtual channel to have a complex mix and two mixers. The first mixer has a mux type of replace, a fixed curve and a scale of -100. This is our default state of "off". The second mixer uses GEAR1 as a source, with a switch of FMODE2. The mux type is replace and the curve is min/max. When FMODE2 is on - so you're in loiter mode - this will replace the -100 output with the value of GEAR1, which will be on if GEAR1 is on and off otherwise.

Next step - we want to ignore the sticks when this switch is on. This is easy. In the channel config (what you get when you select the channel name in the mixer page), set the safety switch to the virtual channel created above, and the safety value to 0. That will cause zeros to be sent on the cyclic channel when you're in loiter mode, which for some flight controllers is required to stay in loiter mode.

Finally, we want to enable the gimbal channels when the switch goes on So we need a complex mix on those channels. You may have some other controls on those - fixed positions, or follow a switch, or whatever. One option is to hold their old position. To do that, make the first mixer a replace mixer, source is the channel it's on, curve is 1-1, scale 100, offset 0. To get the sticks to control it, add a mixer after whatever you're doing on that channel when you're not controlling it with the stick. Set that mixer to have a mux type of replace, a source of appropriate cyclic, and a switch of the virtual channel created above, You can then set up the curve to properly control the gimbal with the stick.]]>TutorialsThu, 12 Nov 2015 16:35:45 +0000Battery mod Devo7e - by: Preethttps://www.deviationtx.com/forum/how-to/1455-battery-mod-devo7e?start=40#39825

Is there a problem with the ripple?

Hello
I was really hoping that you would elaborate on your RJ45 Mod Munin.
Perhaps an overview of your build process will generate more interest.
I'm speculating that your purpose behind this mod was to not install any
rx modules internally?

Well hope to hear from you and your 11 months of experience with your mod.
Easy

Step #1 - Find a suitable image of the model.
I use Google (Images) to search for a picture of the model that
1) Is against a white background with no shadow
2) Is a good fit for the ratio of 52x36 pixels

Step #2 - Size and position image
Then I use MS Paint to size and position the model on 52x36 pixel image size. To do this, I use the
"Resize" command to decrease either the width to 52 or the height to 36. After you do this, you will
probably have to manually resize the canvas to make it exactly 52x36 pixels. Just grab the handle at the edge
of the image and drag it until the size is right. Finally, I use the selection command to move the image into
the center of the canvas. Save the image.

At such a low resolution it will not look great, but as long as the model has
colors other than white, it will come out when converted to B&W.

Step #3 - Change to a high contrast B&W icon
Then I open the image from Step #2 in Gimp. Then I select the "Threshold" function
from the "Colors" menu. As you manipulate the slider on this function, different brightness
of colors are converted to black or white. Find the best setting that makes the icon
appear complete and clean. Click OK to have the function changes take affect on the image.

Step #4 - Exporting to the correct format
Then I am ready to export a bitmap by selecting "Export..." from the "File" menu. Here
you have to type in a filename for the new bitmap file. By giving it an extension of BMP,
you will get the following options when you click "Export".

You have to check the "Do not write color space information " and select "R5 G5 B5" under "16 bits" .

That's it! The exported file can be moved to your modelico folder where it can be picked up

This actually comes from working with RC yachts. So I start with an explanation for those not familiar with RC yachts. Others may skip to the next section.

Most RC yachts have two sails, a mainsail and a jib. Each is attached to a boom at the bottom. The boom has one end attached to something solid, and the other end free to swing with the wind, to the limits determined by a line called a sheet. The length of the sheet - and hence the angle the sail will take in the wind - is controlled by a servo or winch that you control remotely.

Generally, the sheets for both sails are controlled by a single servo, as the two sails having the same angle works fairly well. However, the ability to trim the two sails independently can result in better performance. So some classes of model yacht racing allow for a one servo per sail. You still want one stick to control both sheets, but each servo to have a different trim setting.

The goal

While there are instructions on the web for modifying a stock transmitter to allow a single stick to control both the jib and mainsail sheets, with each having it's own trim, the results seem less than optimal. The control stick runs diagonally, and you wind up losing the other direction for that stick, meaning you can't control the rudder and sheets with one stick.

Given a modern computerize transmitter, you can easily have one stick control two output channels. With deviationTx, you can also have the two channels have separate trims. In particular, you can have the ability to have one trim that trims both sails and a second that only trims one, just trim one of the two sails without trimming the other, or independent trims for each sail.

Trimming outputs

The default settings for the trims in deviation are to trim inputs. However, these can also be set to trim arbitrary inputs, or even outputs.

To get started, create an empty model, and set it to four channels. We're going to assume the protocol order is Elevator, Aileron, Throttle and Rudder. Go to Model Config > Mixer, click on the Simple button next to ELE, and change the input to THR. This will make the output of channels 1 and 3 follow the throttle stick, and the elevator stick is ignored. You can check this on the Transmitter > Channel monitor page.

We'll now create the three trim models discussed above, with three simple changes.

Second servo output trim

Right now, the throttle trim buttons will trim both channels, and the elevator trim buttons. like the elevator stick, do nothing. Let's fix this. Go to the Model Config > Trims page, and select the ELE button, and then change the Input to Channel 1, or whatever channel the elevator stick output went to originally. Now the Elevator trim buttons will change channel 1 but not channel 3. The Throttle trim buttons still change both.You can verify this on the Channel Monitor page.

Single trim

Next, go to Model Config > Mixer, and select the Simple button next to THR. Change the type in the top row to Complex, and then select Trim to change it to No Trim. This disables the Throttle input trim on this channel, so there is no way to trim the Channel 3 output. Channel 1 is still trimmed by either the Throttle trim or Elevator Trim buttons.

Split trims

Now let's enable the Throttle trims for just channel 1, not both 1 and 3. Go back to Model Config > Trims, and select the THR button. Change the input from THR to Channel 3 or whatever channel originally got the THR output. Now the throttle trim just controls Channel 3, not both channels, and the elevator trim controls channel 1. Note that this happens even though the Channel 3 mixer has trim disabled!

This change will work if the Channel 3 mixer was not changed as in the Single Trim section above.]]>TutorialsMon, 20 Apr 2015 06:44:20 +0000Antenna replacement Devo 7e - by: 30secshttps://www.deviationtx.com/forum/how-to/1881-antenna-replacement-devo-7e#30335

I'm planning on installing the NRF module with the swivel antenna as the main one. Can you provide some more info on how about to do that? Sould i cut the top then slowly try to wedge the antenna base and continue to "shave" the plastic until it's a tight fit?

How did you do it?]]>TutorialsFri, 27 Mar 2015 16:42:40 +0000Devo 10 bind to E Sky EK2-0708 (Esky Big Lama) - by: hexfethttps://www.deviationtx.com/forum/how-to/3959-devo-10-bind-to-e-sky-ek2-0708-esky-big-lama#28838

I think a custom OP module for sending a simplified telemetry down would be the way to go. The Deviation firmware supports telemetry for some other radio protocols, so emulating one of those would be easiest. You would also want to make it fairly low data rate so that it wouldn't reduce range.

BTW, I've been playing with some new hardware designs that you can see a bit of on my
blog
. I've got some more to add to it, but I've been busy lately and haven't added it. I have a OPLink-like board that goes with the flight controller, and a new module that I built for my Tx that includes an RFM23BP and nRF51822, which adds nRF24l01 and Bluetooth low-energy. This would allow e.g. direct logging of telemetry to a PC/Tablet/Phone.]]>TutorialsFri, 10 Oct 2014 21:42:32 +0000Assigned Channel to a Switch - by: mikemacwilliehttps://www.deviationtx.com/forum/how-to/3586-assigned-channel-to-a-switch#26020
